Then, we use traditional neural networks and various machine learning methods for training, including KNN (K-Nearest Neighbor (N = 15)), LR (logistic regression), SVM (Support Vector Machine), NB (Naive Bayes classifier), DT (decision tree), RF (Random Forest), MLP (multilayer perceptron), RBFNN (Radial Basis Function Neural Network [29]). 3) and then divided it into two parts depicted in detail in Figs. Fidelity of the HSCNN+ model in maize spectral recovery application. They cannot answer future land use issues, such as future climate change, including the availability of water resources, and the introduction of new crop hybrids. Crop phenotypic traits are the intuitive expression of the suitability between crop growth and current land, and the result of the interaction between environmental factors such as soil and climate and crop varieties. The authors propose a deep learning model AGR-DL based on CNN and RNN. The subsequent use of a two-stage transfer learning strategy to train CENet models of disease images in complex contexts allows for faster training of the models while ensuring accuracy. Nguyen, C., Sagan, V., Maimaitiyiming, M., Maimaitijiang, M., Bhadra, S., Kwasniewski, M. T. (2021). The first one is to build relatively shallow learning models or sparse coding from a hyperspectral prior (Robles-Kelly (2015); Arad and Ben-Shahar (2016); Aeschbacher et al. Feng, L., Wu, B., Zhu, S., Wang, J., Su, Z., Liu, F., et al. In addition, 375 × 500* is the maximum input size supported by LS-RCNN, and GoogleNet* is the GoogleNet with the method proposed by Hu et al. However, the traditional machine learning method has some shortcomings, such as limited learning and expression ability, manual extraction of features, and unsuitable for processing large amounts of data.
In this paper, we propose a new method based on cascade networks and two-stage transfer learning to identify maize leaf diseases in natural environments. The notation "1 × 1" and "3 × 3" denote the convolution with the kernel size of 1 × 1 and 3 × 3 respectively. A general graph convolution structure can be represented as shown in Formula (2), which consists of 2 basic operations, aggregation and update, and corresponding weights. Smallholder farmers in Village M—a farming community south of the eastern border city of Mutare in Zimbabwe—have, for years, enjoyed bumper harvests of maize and other crops.
Therefore, making a tradeoff between the recognition accuracy and time spent during training, Resnet50 network demonstrated the best performance and was used for further optimization on datasets with complex backgrounds. Hinton, G. ImageNet Classification with Deep Convolutional Neural Networks. At present, using artificial intelligence technology to improve suitability between land and crop varieties to increase crop yields has become a consensus among agricultural researchers. Ethics declarations. The overall framework is as depicted in Figure 2.
First, the novel spectral recovery disease detection framework which has provided a new way of thinking for plant disease detection is proposed. Normally, owing to the measurements of hyperspectral camera are performed based on the line scanner, the time to obtain HSI data is much longer than get RGB image by digital camera (Behmann et al. In addition to verifying the quality of the spectral recovery model through the above evaluation metrics, we utilize a pest-infected maize detection model to test the effectiveness of the spectral recovery model. Finally, the accuracy rate slowly increases and tends to be smooth, and the model converges.
